Replace tnt2 springs with new vpi isolators?

Ask Mike about the squash ball suspension for your table. It's really the very best solution. If you're handy Mike will sell you the parts so you can continue to use the four cups you already have. Then it's not a very expensive proposition.

I'm talking TNT. I'm talking about something I've already done. Go to http://www.elusivedisc.com/prodinfo.asp?number=HW-A1216

There you will see what I am talking about. However they want to sell you new "cups" at the 4 corners of the TNT. But all you really need is what is shown with the ball on top. The ball will rest against the top of the cups you already have but you may have to experiment with spacers. I made spacers out of wood. Under the ball there are two plastic parts that screw together allowing adjustment for height.

This is the arrangement that VPI has used to replace the bladders on the high end TNTs. It works great.

Yes, that's it. The reason the "kit" includes new stainless steel cups is that they are sized to make everything come out at just the right height. But they are the most expensive part of the kit. If Mike will sell you just the plastic gear below the ball (and the ball) you will have to experiment with spacers to make the whole thing come out at the right height. I used double sided tape to hold wooden spacers in the cup. It took me two tries, but it came out perfect. It was a clear improvement over the springs. Good luck!
